  1. 1. Machine Learning for State Estimation in Fighter Aircraft

    University essay from KTH/Optimeringslära och systemteori

    Author : Axel Boivie; [2023]
    Keywords : State estimation; machine learning; fighter aircraft; neural networks; long short- term memory; LSTM; sensor fusion; air data system; ADS.; Tillståndsestimering; maskininlärning; stridsflygplan; neurala nätverk; sensorfusion; luftdatasystem.;

    Abstract : This thesis presents an estimator to assist or replace a fighter aircraft’s air datasystem (ADS). The estimator is based on machine learning and LSTM neuralnetworks and uses the statistical correlation between states to estimate the angleof attack, angle of sideslip and Mach number using only the internal sensorsof the aircraft.

  3. 2. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  4. 3. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE

  5. 4. Weight prediction of flight control subsystem

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Joel Lundahl; [2022]
    Keywords : Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

    Abstract : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. READ MORE

  6. 5. Weight Prediction of the Environmental Control System for Fighter Aircraft

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Lager; [2022]
    Keywords : Air Cycle Machine; Environmental Control System; Fighter jet; Military aircraft; Weight prediction; Luftcykelmaskin; Kylsystem; Militära flygplan; Stridsflygplan; Viktprediktering;

    Abstract : Aircraft design is heavily reliant on weight characteristics of the vehicle, and predicting the weight of subsystems in an early design phase is fundamental. The problem with predicting the weight of aircraft subsystems today is that the number of input parameters do not represent enough level of accuracy to account for different architectural solutions.
